when i was first diagnosed GP told me to have complete rest for 10 days to see if they went away. In about a week i lost use of my hand and with some research i realised it was the worst thing to do. I ty to do lots of gentle movement with my hand and things like typing have been great for my fingers. Its not great when my fingers are sencitive, but i do as much as i can. Over summer, I saw picking tomatoes in the garden as physio. It was great. now I stil have pain but it attempt to use my hand as normal as much as i can and keep it moving through the day. Perhaps you could find activities that keep your hands and fingers moving to use as therapy. I also found hydro therapy good in the beginning. For me it got easier with time. Now with the help of meds, I have good movement with some stifness and only a little pain.
